为确保饮用水中高锰酸盐指数检测结果准确可靠，以GB／T 11892–1989方法《水质高锰酸盐指数的测定》为试验方法，每日对同一质量浓度质控样品平行测定2～3次，统计30组有效数据，通过计算平均值、标准偏差得出上下控制限、警告限和辅助线，绘制出现有实验室人员测试技术水平、试剂、设备、分析方法和环境因素条件下的质量控制图。该质量控制图不仅用于实际检测过程中对检测结果进行监控，还可为实验室的人员分析技能考核、比对监测等分析质量控制行为提供结果判定的依据。

The effective and feasible method was discussed about ensuring the accurate detection result of permanganate index in drinking water. The current national standard Water Quality—Determination of Permanganate Index (GB/T 11892–1989) was used as a detection method. The same quality control sample was determined two or three times everyday, and the effective data of the thirty groups were counted. By calculating the average value and standad deviation of the data, the control limit, boundary limit and auxiliary limit were obtained. With the limits, a quality control chart was outlined, by which the laboratory testing skills, reagents,equipment, analytical methods and environmental factors were taken into account. The chart was not only helpful in controlling the testing results, but also useful in the judgment for quality control activities, such as analysis skills assessment and monitoring comparison.
